衔接理论与大学英语阅读教学

在英语听说读写四大技能中,阅读占有极其重要的地位。提高学生的阅读理解能力,在很大程度上是提高了他们运用所学外语的全部技能。将衔接理论运用于大学英语教学具体实践,可知阅读教学中有意识地运用衔接理论对学生进行阅读策略训练,能够有效地提高阅读理解水平。     

Spoken vocabulary growth: Its role in the development of phoneme awareness and early reading ability

In this paper, two theoretical positionsregarding the developmental origins of thephoneme as a unit for lexical representationand processing are outlined – theaccessibility and emergent positions. OurLexical Restructuring Model (Metsala & Walley1998), which is consistent with the secondposition, focuses on the role of vocabularygrowth in prompting the implementation of morefine-grained, segmental representations forlexical items in childhood; this restructuringis viewed as an important precursor to theexplicit segmentation or phoneme awarenessskills implicated in early reading success.Empirical evidence that supports this model issummarized, including preliminary results fromone of our most recent studies. Severalsuggestions are made for future research thatwill lead to a better understanding of thedevelopment of spoken word recognition and thelinks between speech- and reading-relatedabilities.     

Using lexical chains for keyword extraction

Keywords can be considered as condensed versions of documents and short forms of their summaries. In this paper, the problem of automatic extraction of keywords from documents is treated as a supervised learning task. A lexical chain holds a set of semantically related words of a text and it can be said that a lexical chain represents the semantic content of a portion of the text. Although lexical chains have been extensively used in text summarization, their usage for keyword extraction problem has not been fully investigated. In this paper, a keyword extraction technique that uses lexical chains is described, and encouraging results are obtained.     

论和谐文化与中华民族凝聚力

以和谐为特质的中华文化是中华民族凝聚力的思想基础和源泉。和谐文化通过促进国家统一、民族团结、民族认同,增进民族自豪感,维系海内外华人的民族情,而起到中华民族精神纽带的作用。面对全球化背景下中国社会的深刻变革,增进中华民族凝聚力,必须坚持和谐理念:用和谐理念正确处理中华文化与各种地域文化发展的关系;用和谐态度正确对待外域文化;法治文化与和谐文化相融合。在中国和世界范围内,使中华文化的核心价值——和谐得以延伸,是我们光荣的历史使命。     

Authorship attribution based on a probabilistic topic model

This paper describes, evaluates and compares the use of Latent Dirichlet allocation (LDA) as an approach to authorship attribution. Based on this generative probabilistic topic model, we can model each document as a mixture of topic distributions with each topic specifying a distribution over words. Based on author profiles (aggregation of all texts written by the same writer) we suggest computing the distance with a disputed text to determine its possible writer. This distance is based on the difference between the two topic distributions. To evaluate different attribution schemes, we carried out an experiment based on 5408 newspaper articles (Glasgow Herald) written by 20 distinct authors. To complement this experiment, we used 4326 articles extracted from the Italian newspaper La Stampa and written by 20 journalists. This research demonstrates that the LDA-based classification scheme tends to outperform the Delta rule, and the χ² distance, two classical approaches in authorship attribution based on a restricted number of terms. Compared to the Kullback–Leibler divergence, the LDA-based scheme can provide better effectiveness when considering a larger number of terms.     

汉语框架网络知识本体构建研究

汉语框架网络知识本体是以框架语义学为理论基础,有丰富的语料库支撑,揭示了概念的本体关系。其获取,是在构建语料库的基础上,利用叙词表、分类表和其他知识分类体系等现有的知识本体,识别领域内外相关的概念并抽取相应属性,建立概念之间的关系,并利用所识别的概念和关系创建新的本体,融合已有的本体和新建本体。图2。参考文献4。

语篇语法与精读课一体化模式探讨

语篇语法脱离了句法层面的分析,从超句的层次把握句子和段落之间的关系,解读语流中话语或篇章的含义。文章基于语法三大元功能之语篇功能的理论基础,探讨了主位结构、信息结构、衔接系统在英语专业精读课上的应用,并联系语境分析把握语篇外部环境对语篇的影响,改变传统语法课的教学模式,使语法课与精读课一体化,更有利于语法教学的持续、有效开展。     

英语写作中语块使用的实证研究

提高英语写作技能是英语教学的目标之一,但怎样提高写作水平是英语教学亟待解决的难题。将语块理论引入写作教学,为其提供了新的视角。采用SPSS17．0对140名学习者在写作中使用语块的数据分析,发现其特征如下：从语块使用频度上看,语块使用较少,仅占全文的1/3;从语块使用重复率上看,其重复率较高,接近语块总数的1/3,这表明学习者语块使用不够多样化,种类不丰富;从语块类型上看,短语语块使用较多,句子语块使用较少;从学习者水平上看,高分组限制语块使用较多,低分组固定语块使用较多。
